[分享]：自己做了个屏幕选择填充的程序,给大家分享~~

void Myfa()
{
ads_name ents,ent;
AcDbObjectId objId;
AcDbEntity* pEnt=NULL;
AcDbObjectIdArray dbObjIds;
acedSSGet(NULL,NULL,NULL,NULL,ents);
long len;
acedSSLength(ents,&len);

AcDbHatch* pHatch = new AcDbHatch();
for(long i=0;i <len;i++){
acedSSName(ents,i,ent);
acdbGetObjectId(objId, ent);
dbObjIds.append(objId);
}
acedSSFree(ent);
acedSSFree(ents);

AcGeVector3d normal(0.0, 0.0, 1.0);
pHatch->setNormal(normal);
pHatch->setElevation(0.0);
pHatch->setColorIndex(3);
pHatch->setPatternScale(2);
pHatch->setPatternAngle(0.0);
pHatch->setPattern(AcDbHatch::kPreDefined, "ANSI31");
pHatch->setHatchStyle(AcDbHatch::kNormal);
pHatch->appendLoop(AcDbHatch::kExternal, dbObjIds);
pHatch->draw(); //更新实体
pHatch->recordGraphicsModified(Adesk::kTrue);
// Set Associativity
//
pHatch->setAssociative(Adesk::kFalse);
pHatch->evaluateHatch();
acedUpdateDisplay();


AcDbBlockTable *pBlockTable=NULL;
AcDbBlockTableRecord *pBlockTableRecord;
acdbHostApplicationServices()->workingDatabase()
->getSymbolTable(pBlockTable, AcDb::kForRead);

pBlockTable->getAt(ACDB_MODEL_SPACE, pBlockTableRecord,
AcDb::kForWrite);
pBlockTable->close();

AcDbObjectId HatchId;
pBlockTableRecord->appendAcDbEntity(HatchId, pHatch);
pBlockTableRecord->close();
pHatch->close();
}

不过选择多个实体填充的时候还有问题,百思不得其解:(

binbin

pBlockTableRecord->appendAcDbEntity(HatchId, pHatch);第一次返回ok,第二次就不是ok了

不是很明白，应该怎么改啊？

不大看得懂，我是初学！

选择多个的时候不能填充，请朋友们帮忙看看
